5.3.1

CHANGES:

• Made reference counting of database handles atomic for thread-safety. Thanks
  to Christoph Wintersteiger for the suggestion, and to o3-mini-high for
  finding a reference counting bug when handling exceptions.
• Fixed collation link freeing bug. Thanks to o3-mini-high for suggesting the
  fix without even being prompted (minus-shot).
• Removed obsolete compiler flags. OCaml already passes optimization flags, and
  flags for position-independent code should not be necessary. Thanks to Jonah
  Beckford for the contribution.

  Thanks to Yawar Amin [email protected] for this contribution!

5.0.3

CHANGES:

• Fixed missing GC registration of init values in aggregate functions.

  • Fixed call to final aggregate function when no step function was called.

  • Fixed incorrect required minimum OCaml version (now 4.12).

5.0.2

CHANGES:

• Added missing dune-configurator dependency.

  • Removed redundant build dependencies.

  • Use caml_alloc_initialized_string wherever possible.

  • Fixed documentation typos and wording.

  • Added support for const char strings in stubs due to stricter handling

5.0.1

CHANGES:

• Added missing :with-test declaration in Dune project file.

  • Improved portability to older SQLite3 versions.

5.0.0

CHANGES:

• Breaking change:

    that non-string data will be converted to strings.
  

  • Added support for SQLite3 window functions.

  • Added Sqlite3.Rc.check and Sqlite3.Rc.is_success for easier return
    code checking.

  • Added Sqlite3.prepare_or_reset for reusing prepared statements in loops.

  • Added Sqlite3.iter and Sqlite3.fold for more convenient handling of
    row data.

  • Added more data conversion functions, also for direct access to column data.

  • Added more data binding functions.

  • Improved closing behavior of database using new SQLite3 API.

  • Improved testing framework using ppx_inline_test.

  • Each test case now has its own database for parallel testing.

  • Switched from caml_alloc_custom to caml_alloc_custom_mem.

  • Switched to OPAM file generation via dune-project.

  • Improved compatibility with older OCaml versions. Thanks to Simon Cruanes
    for this patch!
